VALVE.

Application tiled January 31, 192e. Serial No. 689,756.

To all whom t may concer/n:

Be it known that l, FRANK R. MoGnn, a citizen of the United States, and resident of Steubenville, in the county of Jefferson and State of Ohio, have invented certain new and useful lmprovements in Valves, of which the following is a specification.

This invention relates to valves and more articularly to sliding plate valves, and has or its object the provision of a novel form of valve construction, in which the valve seats, or at least one of the valve seats, are moved into sealing engagement with the valve.`

Another object ot this invention is to provide a novel operating 'mechanism for moving the valve seat or seats.

y A further object is to provide a valve construction having the novel arrangement, construction and design of parts hereinafter described in detail and illustrated in the accompanying drawings.

ln the drawings, Figure 1 is a side elevation of a pipe line having my improved valve mounted therein.

Figure 2 is an end elevation thereof.

Figure 3 is a transverse sectional plan on the line llllll of Figure 2.

Figure t is a topplan thereof.

Figures 5 and 6 are fragmentary details showing the valve seat operating mechanism.

Figure 7 is a fragmentary-detail or a modied construction in whichla dierent form ot dexible mounting is shown for the movable valve seat.

Figure 8 isa Ylragntentary` detail ol a lmodied construction, in which both valve fings, the letter A designates the pipe line,

which may be composed of any number of sections secured together in any well known re 1l is a sectional detail showing amanner. The two sections 2 and 3, shown in. the drawings, are spaced apart to form a valve-way d. Each of the sections 2 and 3 is provided with an annular flange 5, which may be riveted, bolted, or otherwise secured to the sections. rlhe anged ends of the pipe sections are held inl spaced relation by separator members 6.

'lhe flange 5 on the pipe section 2 has an annular extension orl valve seat member 7 rigidly secured thereto, and the ange 5 on the section 3 has an annular extension or valve seat member 8 secured thereto through a 'exible web plate 9, so as to provide :for movement ot this seat member in a direction parallel with the longitudinal axis of the p1pe.

A valve plate 10 of the goggle type is mounted between the seats 7 and 8 and is adapted to be reciprocated relative thereto.

rlhe valve seat members 7 and 8 are provided with pull rod anchors 11 and 12, respectively, at spaced intervals and to which are astenedkpairs of pull rods 13, which extend parallel to the pipe line A and away from the center line of the valve 10. 'lhe outer ends ot each'pair of rods 13 are connected by cross heads 14, which cross heads are connected to the opposite ends of a thermal expansion and contracting pipe member 15;. While l have shown four sets of these expansion and contracting units, it will be understood that the number of units may be varied, as desired. i

The purpose ol these expanding and contracting units, is through thermal/application, to cause the pipes 15 to lengthen or shorten as required, they being connected through cross heads 14, pull rods 13, and pull rod anchors 11 and 12, to the stationary or rigid valve seat 7 and the movable valve seat 8, thus transmitting the amount of movement equal to their longitudinal eX- pansion or' contraction to the movable seat 8, moving it toward or away from thejvalve plate, to orm a seal with or to break the seal with the valve, according to the movement of the pipe. p

Attached to the end of each pipe 15 is a nut 16, bearing against the cross head. These nuts 16 serve to adjust the relative position of the movable valve seat 8 to the pipe 15, so as to insure contact with the valve plate 10 of suilicient pressure to form an effective seal. Also, the nuts 16 provide a means of hand operation in case of failure Iof the thermal supply.

The thermal expansion and contracting pipes 15. are connected at pne endfto supply 41 instead olf the ilexible web plate as -in the main construction. It vwill be readily seen that du'e to the one endof' the pipes 15 being pisitively anchored on the -pipe conduits 18, which are connected toasupsection 3 an'y7 expansion or contraction of Y ply main 19 having branches20 and 21 leadever, are fastened at one end to the f ing to sources of supply of heating and cooling mediums, respectively. Suitable valves 22R and 23 are provided in the branch mains 20 and 21, respectively, to controlthe flow therethrough.

The opposite or outlet ends y.to outlet conduits 24 connect to a single escape main 25 which leads to assewer o'rotfh/er point of disposal; 2

The goggle plate 10 is adapted to be reciprocated by the followiri mechanism. Secured to the upper end of t e valve plate 10 is a steel frame 26 (termed valve plate stem) with a lifting chain cross head 27 fastened to the frame at a point slightly above the valve plate, so as to provide \a clearance for adjustment of the valvelifting chains 28 which are secured to the cross head. The chains 28 extend kupward and are wound on and secured to a valve operating druin 29. Also secured to and wound upon the drum 29 is a counterweight chain 30 on which is carried a valve plate counterweight 31.., llhe coun-terweight 31 balances the weight of the valve plate l0, and limits the operating power required to move the valve plate to that required to overcome friction in the operating mechanism. Also secured to and wound upon valve operating drum 29 is a pull back chain 32 which extends upwardly to a ypull back chain crosshead 33, and on which chain 32 is su ported by a chain tension spring 34. As va ve lifting-chains 28, counterweight chain 30 and pu back chain 32 are all attached to a common operating drum 29, the combination with valve plate stem 26 permits of a novel compact operating mechanism, avoiding exposed gears, racks', etc., which, are dillicult to keep in operating condition in many locations. Valve operating drum 29 is rotated by an enclosed gear reduction set operated by a hand chain sheave 36 and/a hand opera-ting chain 37. This drive, .instead of being hand; operated may, of course, be operated by any suitable power device. v l

Referring to the modified construction of or other similar mechanism shown here, ycurrent.

the ipes 15 will be communicated directly to t e scat 8, and thusmove it toward or away from the valve.

In Figure 8 I have seats 7 and S as Ibeing rigid and secured directly to the pi e sections 2 and 3, andJ the thermal expan ing and contractin pipes 15 are secured at each end to anc ors 4,3 on the pipe sections 2 and 3. This construction \is rimarily for use with pipelines having exible or eXpansi-blejoints of any well known construction, so that expansion or contraction of the pipes 15 will move vthe pipe sections bodilysuicient to cause sealing and unsealing of the valve seats.

The pipe sections 2 and 3 are kept' in valinement by the flexible alining plates 44,

which are secured to the seat members 7 and The sepa- 8 and to 'a separator plate 45. rator plate is provided with anchors a6 which are rigidly secured to the pipes l5. vln Figures 9 and l() a further modied form of my invention is` shown, in which the pipe sections 2 and 3 are adapted to be moved bodily. ln this construction the pipe line is shown supported on a rigid column 48, which has a exible connection throh plates e9, with the pipe sections. 'lhe ermal expansion pipes 15 are secured to anchor brackets on the pipe sections 2 and 3 as described for Figure 3 and serve to bodily move the unseal. the seats 7 and 8 with the valve plate 10. l i

,"lhe pull rods 13 are omitted from each of the constructions of Figures 7 and 8, since the pipes 15have at least one end anchored direct to onevof the pipe sections. A

In Figure' '11 I have shown an enlarged detail of a construction which is' an exact duplication of the construction of `Figures 1 to 4, with the exception thatV the pipe or rod 15 is uipped for heating by electric e pipe 15 may be o any deor material suitable for expan- When the pipe sired sha sion by e ectricalheatin or rod 15 is to be heate bti-.electricity the v ipe or rod 15 must be insulated as at 52, rom the cross heads 141 InFigure 12 I have shown a detail 9j? pipe sections to seal and` 152.
